I 3e it known thatI, Moonr. C; HINTON, a c t zen of the United States,residing at Hinton, in the county of Summers and State of West.Virginia, have invented new and useful Improvements in CarrBra-kes, of

My ;i nvention.re ates to'certain new and useful mprovements in carbrakes and cons:1sts in the novel'combmatlon and arrangeparticularlydescribed and pointed out in the claims. 1 g :'In the drawings: Figure'lisa front elevation of my complete invention. Fig. 2 isa detail Viewshowing the train pipe and valve connections formin apart thereof andsecured-to the usual Frame of the car. Fi 3 is a vertical longitudinal-section (alien through .the train pipe and valve forming a part thereofand constructed accordin to my invention taken on the line w-w of Fig 2.Fig. 4 is a transverse section taken on in connection with the drafttimbers o the car and used in connection with a valve lever;

.a very simple, practical and effective up aratusfor automaticallycausing the bra 'es to be operated or set on a car or train, should thebrake beam or other rigging placed, inoperative or dropped to assume aof t 'e car or train.

' The invention therefore consists of a chain or other yieldingconnection attached tothe arch or brake beam, and in a movable andoperative connection with'the suitable valve located in the train pipe,whereby the accidental displacement of the brake beam or rigging formingapart of the latan escape of air 1n the train pipe and simultaneouslysetting tire train to which m invention is applied. Referring to therawings, 1 represents an ordinary car having the usual wheels 2, shaftor axle 3 and 'boxes 4, all of which is of the ordinary construction.The brake beam 5 is also of the usual conva ve casing nature of mautomatically set the bra slotted, through whi struction' and issuspended from the draft rigging of the car in the usual and wellknownmanner and is provided with the ordinary brake shoes.

Passing through the brake beam 5and secured thereto 1n any suitablemechanical manner are eye-bolts 6 to which are secured the .op ositefree ends of the chain -7, the

latter eing adjustable along its length by turn-buckles 8, the unitingendsof said chain terminating ata common center and being attached tothe free end of the lever 9, all of which Willbehereinafter more fullydescribed. By referring particularly to Figs. land 2 of the drawings, itwill be seen that the train pipe 10 is of the -usual construction :andin carrying out my invention the same is rovided along its length orbelow the b0 y of the car with a tubular extension 11 within which islocated a valve plug 12 having a longitudinal port 13 in communicationwith the train pipe and a horizontal rt 14, the outer end of which isada t to re ister with the opening 15 forme in the 16. a i I The valveplug 12 may be of anysuitable design or construction and to the outerprojectmgend'of which is secured a lever 17 to the free end of which issecured the opposite connecting ends of the chain 7 leading from thebrake beam 5 of the brake ri in l do not limit myself to the precise0011'- struction of the valveherein shown and.

described, as the same may be modified in.

many respects without departing from the invention and referringparticularly to 3 of the drawings it will be seen that threaded cap 18to close the upper projecting tubular extension 19 forming a part ofsald valve, the principal object, as before'stated,

being to cause an escape of air in the train pipe should there be anyaccidental dishave employed ascrew lar bar also having a slot 23 forfreely receivmg the lever 9 when the latter is oper- "ated in itsdownward movement.

From the foregoing description it will be seen that when the brake beam5 is in its normal or operative position in respect to the wheels of thecar the valve will be in a closed position to prevent any escape of airfrom the train pipe, but should the said brake beam drop or becomedisplaced from its normal or proper position, the said valve will beautomatically operated causing the port in said valve to register orcommunicate with the opening 15 of the valve casing,

- thereby allowing an escape from the train pipe and causing the brakeof the particular car or train to be automatically set, all

of which is of the usual and Well-known construction.

Having thus described the invention what is claimed as new is:

1. A. car brake comprising a suitable valve in communication within thetrain pipe, and suitable means connected with said valve and with thebrake beam of a car, as i v and for the purpose described. I

2. A car brake comprr'ng a sultable valve communicating with and forminga part of the train pipe, and suitable means 1 attached to said valveand also to the brake i beam of a car, whereby when. said brake i beamis accidentally displaced the said valve is automatically operat'edforpermitting an escape of air from the train pipe, as and for i i thepurpose described.

3. A" car brake comprising a suitable valve having a longitudinal andtransverse port formed therein and adapted to register .1

k thereof for the escape of air, a chain having i its opposite endattachedto the brake beam 5 of a car and removably connected to a suit-'1 able lever forming a part' of said valve for operating the latter, anangular plate one in presence of two witnesses.
